Discussion highlights lost equivalence in gravity theories, indicating a need for clearer research standards.
Triggered by some recent studies within the framework of nonmetricity gravity, I discuss how the basic information regarding the equivalence of the gravitational theories forming the “Trinity of Gravity” has been lost in parts of the literature. As a result, several studies with focus in modified theories of gravity have research investigated the case of STEGR/GR, often without acknowledging this fundamental equivalence or recognizing that their results can be derived in GR.
